Abstract:
What is disclosed is a novel system and method for retrieving a gamut mapping strategy from a seed profile of a seed device. In a manner more fully described herein, the present method provides an embodiment which accounts for the pathological case of a false gamut mapping ray being produced in those instances where the shapes of the gamuts of the host and seed devices are substantially different. In these instances, the rays miss the boundary surface of the host gamut and intersect the boundary of the L*a*b* cube. Another embodiment is provided which accounts for those cases wherein the ray intersects the host gamut at a substantially oblique angle such that mapped color is sufficiently different to generate contours in the output print.
